CUTTING-DIE FOR BOX-MAKING MACHINES.

SPECIFICATION forming part of Letters Patent No. 455,015, dated June 30,1891.

Application iiled January 7, V1891.

To all whom t may concern:

Be it known that I, JAMES F. GILLILAND, a citizen of the UnitedStates,residing at Adrian, in the county of Lenawee and State ofMichigan, have invented certain new and useful Improvements inCutting-Dies for BOX-Making Machines, of which the following is aspecification.

My present invention consists in the construction and arrangement of thedies for use in the box-making machine for which I have made a separateapplication, Serial N o. 37 6,983, for Letters Patent of even dateherewith. Said die consists, generally speaking, in a set of toothedclamps, theY teeth on each of which are arranged to proj ectin betweenthe teeth on the other, and a series of cutting blades or edges,preferably formed of sheet metal, adapted to be held between the varioussurfaces of said clamps, or any modification of this arrangement wherebythe surface of the die as a whole is made to consist of a series ofspaces, each of the shape and size of one of the matching projectionswhich it is desired to form upon the ends of the portions or sections oflumber which are thereby iitted for use in building the boxes to bemade.

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similarl parts,Figure l is a side elevation of a die embodying my said invention; Fig.2, an under side plan thereof, showing the operatingface of the die;Fig. 3, a horizontal sectional View on the dotted line 3 3 in Fig. l;Fig. 4, a transverse sectional View on the dotted line 4 4 in Fig. l;Fig. 5, a perspective view of a cutter portion in the form I prefer toconstruct it, (with two sections in one piece 5) and Fig. 6, a similarview showing a cutterportion formed with a greater number of sections inone piece than are commonly used, although such a construction ispracticable. By section, as above used, -I mean that portion of thecutter the cutting-edge whereof extends from one point to another in astraight line.

In said drawings, the portions marked A represent the head or block ofthe die, B B the cutter-clamps, and C the cutter or cuttingsections.

The block A is of a form to be secured to Serial No. 376,984. (Nomodel.)

the plunger of a press. In its lower side is formed a channel or groovein which the cutter-clamps are secured, antliwliereiu said cutterclampsare secured by means of set-screws a, which are provided in suiiicientnumber to insure that said clamps shall be held firmly against saidcutters at all points throughout their length. This is best shown inFig. 4.

Theclamps B B are toothed on their adjacent faces, the spaces betweenthe teeth being equal to the thickness of the teeth plus the thicknessof two of the cutter-sections, so that when brought together the cuttercan be slipped between them, as shown most plainly in Fig. 3, and thereheld securely in position to operate. Y Small projections b (see Fig. 4)are preferably formed on the faces of the teeth, which pass intocorresponding holes or depressions in the cutter-sections when theclamps are brought together, thus insuring that said cutter shall beheld in place. As above stated, the Vclamps are held into the head orblock of the die bythe setscrews a, which are adapted to be turned uptightly against one of them, and thus clamp them securely in the channelor groove in which they are placed.

The cutter or cutting-edge is preferably composed of several sheet-metalparts, which 'j are placed between the clamps B and there held in thearrangement shown. As shown in Fig. 5, two sections of the cutter arepreferably made in one piece, although each section may be madeseparately, if desired. A greater number of sections may also be lmadein a single piece, if desired, as shown in Fig. G. Those sections whichface the front edges of the teeth on the clamps have holes ordepressions therein, as shown most plainly in Fig. 4, into which theprojections b on said clamps enter, whereby a reliable union of theparts is secured. These projections and holes or depressions might ofcourse be reversed, if desired, although I find it more convenient tomake them as shown. By the arrangement shown,in which onepiece includestwo cutting-sections, one of which runs in a direction at an angle withthe oth er, each piece may have one of these interlocking devices,otherwise those sections of cutter which eX- tend transversely of thedie could not be By this arrangement the thus secured.

IOO

breaking of one sect-ion does not destroy the whole cutter.

Having thus fully describediny said invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. The combination, in a die, of toothed clamps, the toothed surfaceswhereof face each other and the teeth whereon are arranged to passbetween each other, and a sheet-metal cutter bent to iit between andaround said teeth and arranged to be held by said clamps, substantiallyas set forth.

L. The combination, in a die, of two clamps having toothed faces,projections on the faces of the teeth, a cutter placed between saidteeth, and holes or depressions in said cutter, into which theprojections on the clamps enter, substantially as set forth.

3. The combinaton,in a die, of the head or block, clamps secured in saidhead or block, and a cutter' consisting,- of pieces of sheet metal bentso that the sections are ar ran ged in angular relation, whereby whenthe several parts of the die are assembled the cutting-face consists ofa series of cnt- 25 ting-sections arranged in a regular relation,substantially as shown and described.

4c. The combination, in a die, of a head or block thereto having achannel or groove in its lower face, clamps, the adjacent faces of 3owhich are toothed, arrangedin said groove or channel, set-screws in saidhead or block, whereby said clamps are secured in position, and a cutterconsisting of pieces of sheet metal placed between the teeth of theclamps 3 5 and there held, whereby a seried cutting-face is formed,substantially as shown and described.

In witness whereof l have hereunto set my hand and seal, atIndianapolis, Indiana, this 4o 3d day of January, A. D. 1891.

JAMES F. GLTILAND.
